If angle 4 is 42° and lines M and N are parallel, give a reason why angle 5 is also 42°. (1 point) Responses Angle 4 and angle 5 are alternate interior angles, so their measures must be the same. Angle 4 and angle 5 are alternate interior angles, so their measures must be the same. Angle 4 and angle 5 are interior angles, so their measures must be the same. Angle 4 and angle 5 are interior angles, so their measures must be the same. Angle 4 and angle 5 are corresponding angles, so their measures are congruent. Angle 4 and angle 5 are corresponding angles, so their measures are congruent. Angle 4 and angle 5 are vertical angles, so their measures are congruent.

Answer 1

The correct response is: "Angle 4 and angle 5 are corresponding angles, so their measures are congruent."

If lines M and N are parallel, angle 4 and angle 5 must be corresponding angles, which means they are in similar relative positions with respect to the parallel lines and the transversal. Therefore, their measures must be the same, making angle 5 also 42°.
